- Mix the correct type of coolant with distilled water (50/50 mixture) as per Volvo specifications.
- Fill the radiator and coolant reservoir.

3. Thermostat Replacement

Remove the thermostat housing:
- Disconnect hoses leading to the thermostat housing.
- Unscrew the bolts holding the housing in place and remove it.
Replace the thermostat:
- Remove the old thermostat and clean the mating surfaces.
- Install the new thermostat, ensuring it is oriented correctly.
Reassemble the thermostat housing and reconnect hoses.

4. Radiator and Fan Inspection

Inspect the radiator:
- Check for any physical damage or blockages that could impede airflow.
- Clean the exterior of the radiator to remove debris.
Test the cooling fan:
- Start the engine and allow it to reach operating temperature.
- Check if the cooling fan activates at the correct temperature.
